Abstract
The invention discloses a reinforced flame-retardant POM (Polyoxymethylene) material and a preparation method thereof. The reinforced flame-retardant POM material comprises the following components in parts by weight: 60-80 parts of POM, 10-20 parts of toughening agent, 1-3 parts of coupling agent, 0.5-2 parts of antioxidant and 0.1-3 parts of flame retardant. As thermoplastic polyurethane elastomers, acrylonitrile-butadiene rubber and acrylate with weather-proof functional groups, and the flame retardant of an ammonium polyphosphate and epoxy resin compound are added into the POM material, the toughness and the weathering resistance of the POM material are greatly improved, and the flame-retardant property of the POM material is improved, so that the prepared POM material has a broad application prospect.
Description
Technical field

Background technology
Along with developing rapidly of China's electronic apparatus, automobile, aerospace industry, growing to the demand of the engineering plastics of high strength, high flame retardant.Polyoxymethylene (POM) is a kind of engineering plastics of high comprehensive performance, be that mechanical property often is used to replace non-ferrous metal and alloy to be widely used in automobile, electronic apparatus industry, generally to reach industries such as precision optical machinery and five metals building materials near the material of metal in the engineering plastics.But the ageing resistance by ultraviolet light of POM is poor, notched Izod impact strength is low, weathering resistance is poor, and for further widening the field of its application, numerous research staff improve its performance, but is cost with the performance with the sacrifice other side often.
Summary of the invention
For solving the deficiencies in the prior art, the objective of the invention is to overcome the defective of prior art, a kind of fire-retardant POM material that strengthens is provided.Simultaneously, the present invention also provides a kind of fire-retardant POM preparation methods that strengthens.
In order to realize above-mentioned target, the present invention adopts following technical scheme: a kind ofly strengthen fire-retardant POM material, it is characterized in that, comprise that the parts by weight of following component and each component are:
POM 60-80 part;
Toughner 10-20 part;
Coupling agent 1-3 part;
Oxidation inhibitor 0.5-2 part;
Fire retardant 0.1-3 part.
Aforesaid a kind of fire-retardant POM material that strengthens is characterized in that, described toughner is a kind of in the Polyurethane Thermoplastic Elastomer that contains weather-proof functional group, paracril, the acrylate.
Aforesaid a kind of fire-retardant POM material that strengthens is characterized in that described coupling agent is silane coupling agent.
Aforesaid a kind of fire-retardant POM material that strengthens is characterized in that described oxidation inhibitor is antioxidant 1010, oxidation inhibitor 168.
Aforesaid a kind of fire-retardant POM material that strengthens is characterized in that described fire retardant is ammonium polyphosphate and epoxy resin composite.
Prepare aforesaid a kind of method that strengthens fire-retardant POM material, it is characterized in that, may further comprise the steps:
(1) a kind ofly strengthens fire-retardant POM material and take by weighing each component according to aforesaid.
(2) each component that takes by weighing in the step (1) is put in the high-speed mixer, high-speed mixing is 5 minutes under the condition of 20-30 degree.
(3) mixture in the step (2) is gone out grain through twin screw extruder and make, its condition is: the temperature in each district is between the 160-180 degree.
Beneficial effect of the present invention is: by add Polyurethane Thermoplastic Elastomer, paracril, the acrylate with weather-proof functional group in the POM material, and ammonium polyphosphate flame retardant and epoxy resin composite, toughness and the weathering resistance of POM have not only been improved greatly, and improved its flame retardant resistance, make the POM material of preparation have application prospect more widely.
Embodiment:
The present invention is described further below in conjunction with specific embodiment.
Table 1 is the proportioning of each component of embodiment 1-3 and Comparative Examples.
As shown in table 1:
The proportioning of each component of table 1 embodiment 1-3 and Comparative Examples
Wherein, used toughner is respectively Polyurethane Thermoplastic Elastomer, paracril, the acrylate that contains weather-proof functional group among the embodiment 1-3, and the toughner that uses in the Comparative Examples 1,2 is respectively polybutadiene rubber and polyamide resin.
The used oxidation inhibitor of embodiment 1-3 is respectively antioxidant 1010, antioxidant 1010, oxidation inhibitor 168, and Comparative Examples 1,2 used oxidation inhibitor are respectively antioxidant 1010, oxidation inhibitor 168.
Used coupling agent is silane coupling agent in embodiment 1-3 and the Comparative Examples 1,2.
The used fire retardant of embodiment 1-3 is ammonium polyphosphate and epoxy resin composite, and Comparative Examples 1,2 employed fire retardants are halogen system and phosphorus flame retardant.
Each component in the table 1 is handled according to following steps, then gained POM material is carried out performance test:
(1) the POM material according to a kind of modification in the table 1 takes by weighing each component.
(2) each component that takes by weighing in the step (1) is put in the high-speed mixer, high-speed mixing is 5 minutes under the condition of 20-30 degree.
(3) mixture in the step (2) is gone out grain through twin screw extruder and make, its condition is: the temperature in each district is between the 160-180 degree.
Table 2 is the The performance test results of each embodiment and Comparative Examples, and is as shown in table 2.
The The performance test results of each embodiment of table 2 and Comparative Examples
Annotate: reference standard is: GB13525/T-92 and UL94.
As can be seen from Table 2, from toughness reinforcing and effect weathering resistance, added the Polyurethane Thermoplastic Elastomer, paracril, the acrylate that contain weather-proof functional group among the embodiment 1-3, its toughness and weathering resistance are stronger than Comparative Examples.From flame retardant effect, add ammonium polyphosphate and epoxy resin composite among the embodiment 1-3, its flame retardant resistance is stronger than adding simple fire retardant in the Comparative Examples 1,2, can make flame retardant rating reach the V-0 level.As seen, played the good flame effect.
